気ヘツド。 In a composite floating magnetic head consisting of a non-magnetic slider and a head core that levitates above a magnetic recording medium and performs recording/reproduction on the magnetic recording medium, the head core has a high saturation magnetic flux on at least one side of the gap forming surface of the gap portion. It has a metal-in-gap structure coated with a high-density metal magnetic thin film, and the angle θ between the sliding surface on the air inflow end side that contacts the magnetic recording medium and the gap forming surface on the air inflow end side is 90.
A composite levitated magnetic head characterized by being set at a temperature below
